%28y%5E2%2B7y-4%29%28y%2B6%29 Start with the given expression.


y%5E2%28y%2B6%29%2B7y%28y%2B6%29-4%28y%2B6%29 Expand.


Distribute.


y%5E3%2B6%2Ay%5E2%2B7%2Ay%5E2%2B42%2Ay-4%2Ay-24 Multiply.


y%5E3%2B13%2Ay%5E2%2B38%2Ay-24 Now combine like terms.


So %28y%5E2%2B7y-4%29%28y%2B6%29 expands to y%5E3%2B13%2Ay%5E2%2B38%2Ay-24.


In other words, %28y%5E2%2B7y-4%29%28y%2B6%29=y%5E3%2B13%2Ay%5E2%2B38%2Ay-24.
